Girder 4 compatability

[esajesa]

Hi,

I wonder if there's any plans on making the Girder channel changer compatible with Girder 4?? I know G4 is still in beta, but it's so stable now I've moved over everything else to it, and would love to move over the GBPVR stuff as well.

Cheers,
Jens

There is no plans to change the Girder support in GB-PVR at this stage. I would be surprised if Girder 4 requires changes.

Hi Sub,

well, prepare to get surprised! ;-) The communication protocol in G4 is completely different from G3.3, even a Girder 4 instance can't talk to a Girder 3.3.

Do you have the code for the current Girder support available? I could perhaps take a look and see if I can change it to support G4 myself.

Cheers,
Jens

GB-PVR doesnt talk directly to Girder, instead it just opens a socket (to the internet event server) and sends strings then closes the socket. I would be surprised if they change how I have to pass information the Internet Event Server plugin. That said, if the they've changed the API, then someone will need to update the Internet Event Server, which I'm sure will be done very quickly.

Hi again,

yes, the API has changed. They've gone from using the IES to something called Comserver, which uses a different protocol. I've done quite a bit of developing in Girder, and that's why I offered to take a look at doing the necessary changes.

I've gone over to G4 with my whole setup now, and GBPVR is the last part. I love your product, and this is the last thing I want done for now!

Anyways, let me know if you want/need any info.

Cheers,
Jens

Below is the GB-PVR girder code. I dont personally use Girder, but if you can provide an alternative implmentation, then I'll update it. Otherwise it'll just have to stay broken for Girder 4.

Code:

        public void setChannel(int channel)
        {
            Logger.Verbose("GirderTunerController.setChannel " + channel);
            string channelNumber = channel.ToString();
            if (useZeroPadding)
            {
                channelNumber = channel.ToString("00");
                if (useThreeDigitChannelNumbers)
                {
                    channelNumber = channel.ToString("000");
                }
            }

            Logger.Verbose("channel number: " + channelNumber);

            // send girder events
            TcpClient tcpClient = new TcpClient();
            try
            {
                tcpClient.Connect(host, port);

                NetworkStream networkStream = tcpClient.GetStream();
                StreamReader input = new StreamReader(networkStream);
                StreamWriter output = new StreamWriter(networkStream);
                output.AutoFlush = true;
                output.NewLine = "\n";

                output.WriteLine("quintessence");
                String cookie = input.ReadLine();
                output.WriteLine(getMD5String(cookie + ":" + password));
                String accept_result = input.ReadLine();                

                if (accept_result.Equals("accept"))
                {
                    // send keys
                    for (int i=0; i<channelNumber.Length; i++)
                    {                
                        Logger.Verbose("Sending: GB_TUNE_" + channelNumber[i]);
                        output.WriteLine("GB_TUNE_" + channelNumber[i]);                        
                    }                                        

                    output.WriteLine("GB_TUNE_EON");                        
                    output.WriteLine("GB_CHANNEL_" + channelNumber);

                    output.WriteLine("close");
                }
                else
                {
                    Logger.Verbose("Girder login not accepted");
                }
                
                output.Close();
                input.Close();
            }
            catch (Exception ex)
            {
                Logger.Error("Error sending girder event: " + ex.Message);
                Logger.Error(ex.StackTrace);
            }
            finally
            {
                tcpClient.Close();
            }
        }

hi esajesa,

Just to let you know I'm looking at having to integrate my 2005 MCE remote to GB-PVR via Girder, so its likely I'll be interested in solving this too. (I need Girder to solve the issue with my current arrangement whereby where GB-PVR loses focus + hopefully create extra mappings like to get the mini-guide & OSD functions working within livetv mode)
